Grubwithus is a social dining service where you pick a restaurant in a city that you like and buy a ticket for a meal at a set price. To really make the service work, other people have to buy a meal at the same place and you can coordinate a time to meet at the restaurant.
Grubwithus spun out of Y Combinator last year and raised $1.6 million from Andreessen Horowitz, First Round Capital, SV Angel, Yuri Milner, New Enterprise Associates, Ashton Kutcher, Guy Oseary, Vivi Nevo, Matt Cutts, Maynard Webb, Elad Gil, Paul Buchheit, Alexis Ohanian, and Start Fund.
Grubwithus also highlights charity and raffle dinners on their website. Grubwithus is currently available in Chicago, San Francisco, New York, D.C., and L.A. They will soon be available in Boston and Seattle. Chicago is their biggest city as they started there. They plan to hire more people to their 8 person team as a result of the funding.
